end of the east pit, where any sediment that has been generated from runoff on the pit floor will <br />settle. The water will then discharge from pond into the surrounding natural drainages and <br />wetland. Map C -2 shows the sediment ponds locations. Map C -4 shows the sediment pond <br />dimensions. <br />Since dewatering of an alluvial deposit so close to the central wetlands may lower the ground <br />water level that supports said wetlands, a second pit pump will redirect ground water straight into <br />a standard perforated irrigation pipe that will discharge uphill of the central wetlands. This <br />common operational practice will prevent the wetlands from drying up due to the ground water <br />dewatering. Map C -2 shows the location of these pumps. This pump will also be located below <br />the pit floor, ensuring clean water is what is pumped. These pumps will likely be diesel powered, <br />and therefore... <br />All water rights issues such as availability of water for this operation, consumption rates, dust <br />control, etc. is presented in Exhibit G - Water Information. Sediment control designs are <br />included in Exhibit G. <br />6. Schedule of Operations <br />Mining operations will only occur as dictated by demand up to the maximum rates described <br />earlier in the mine plan. Mining, crushing, and screening may take place 12 months out of the <br />year and product will be sold throughout the year, although less material is expected to be sold in <br />winter months. It is possible that processed material will be stockpiled to allow mining and <br />processing to cease for parts of the year. The Tomichi Pit will operate between 7 am and 6 pm <br />five days a week, with the possibility of repairs being conducted on Saturdays. Special <br />operations may require extended hours of operation. <br />The access will be gated to prevent entry during off hours. <br />Tomichi Pit, December 2013 D -8 <br />
